EYELETING-MACHINE,

Specification of Letters Patent.

Patented Oct. 21, 1919.

T0 all whom 'it may concern f Be it known that I, HARRY I-l. Oseoon, a citizen of the United States, residing at lVorceSter, in the county of Worcester, State of Massachusetts, have invented a certain new and useful Improvement in Eyeleting-Machines, of which the following is a specification, reference being had` therein to the accompanying drawings. y

The invention relates to eyeleting machines of the class constructed with provisions for piercing or perforating the work to receive an eyelet or other like fastener, and for setting such eyelet orthe like in hole or perforation in the work, with or without the addition of a Washer or other complementary fastener-member. f

The main object of my invention is to provide a novel and improved combined piercing or perforating and setting machine of the type in which the piercing or perforating of the work is followed by the setting of the eyelet or other fastener with the work remaining impaled upon the piercer or perforate'r until after the setting operation has been performed. The general aim is to produce a machine providing for easy handling of the work and convenience in the presentation thereof to the piercing and settingl devices for the successive operations, and for enabling the operations of piercing the work, supplying an eyelet and a washer or other complementary fastener-member when one is employed, and setting', to be rapidly performed.

One special object of the invention is to facilitate the application of an eyelet or eyeleted fastener-member to the protruding end of the piercer or perforator of a machine o'f the type just mentioned, after the piercer or perforator has been forced through the work and while it remains engaged therewith. Another is to kfacilitate the application of a fastener-member to the piercer or perforator prior to the piercing or perforating operation,

rEhe invention is embodied in an eyeleting n'zachine comprising opposite relatively movable supports, one thereof provided with a combined piercer or perforator and set and the other provided with means for coperating with said piercer or perforator and set in piercing or' plei'forating and setting lby and a work-backing which in its normal position Covers the piercer or perforator but is positioned automatically to expose the piercer or perforator after the piercing or perforating operation for application of a fastener-member thereto. With the work-backing, adapted to be moved by the work in the piercing or perforating operation to expose the piercer or perforator as just mentioned, is combined means whereby it is latched or locked in the position thereof produced by the piercin or perforating operation, namely, retracte toward the base of thc piercer or perforator and Vwith the piercer-point or perforatorpoint protruding through the work in readiness for application of a fastener-member thereto, as for instance an eyelet, in preparation for a setting operation. This automatic positioning of the work-backing Vin uncovering position facilitates the application of the eyelet or other fastener-member to the point of the piercer or perforator in preparation for the setting operation.

A feature of the invention consists in automatic means whereby the worl -backing is returned to normal position after the setting operation. Specifically, this means preferably consists in means for automatically unlatching or unlocking the Workbacking so as to permit the actuating spring or springs in connection with the workbacking to return the latter to its said normal position. A

Another feature of the invention consists in so constructing and arranging the parts that in the normal position ofthe workbacking a fastener-member laid against its surface may be slid over the opening for the Combined piercer or perforator and set, and passed into place around the said piercer or perforator. e

The accompanying drawings sho-w an illustrative embodiment of the invention.

Fig. 6 is a view in vertical section' in the plane indicated by the line 6, 6, in Fig. 5.

Fig. 7 isa sectional'view on an enlarged scale of the combined piercer and set showing a washer applied thereto.

l and 2 are the opposite relatively movable supports of the illustrated embodiment In such embodiment `the relative movement 'of the supports with respect to each other is provided for by making one support movable toward and from the other, the latter being Yfixed. In this instance the lower support 1 is the fixed one, and the upper support 2 is mounted in guides in the fixed head 3 of the machine, in which-guides it is adapted to be Yreciprocated vertically toward and from the saidfixed lower support. Means Vfor producing the movement of the upper support -towardvand from the lower support is not shown, because it forms no part of the invention. 1n practice, any approved devices or mechanism for producing the said move- Yment maybe employed, either in' the shape of devices transmitting manual effort for the'actuation of the upper support, or in the shape of devicesV or mechanism applying mechanical power at the will of the operator.

The support 1 is provided with the combined piercer and set 4, 4, and the support 2 is lprovided with the means for coperating with said combined piercer and set in piercing and Vsetting by successive operations. Such means mayvary in character in practice. In this instance it comprises a die 5 and a set 6 which, in order that they may be caused'to alternate in their coperation'with the said combined piercer and set 4, 4a, are combined with the movable support 2 in manner enabling them vto be presented alternately in Vworking position in the said successive operation.

Thedie 5 'and-upper set 6 are centrally bored to receive the piercing-spur 4, and the bore of die 5V is enough larger in diameter than the said spur to receive the portion of the material oi' the work Figs, 3 and 4, which is upturned by .theV passage of such spur through the thickness of the wor V1f desired, the piercing-spur may be replacedv by a punch adapted to cooperate with the a hole in the work, in which 'case provision willbe made for the escape-0f the punchings. f

To provide for the alternate presentation of theV die 5 and set' in working position with reference to the combined piercer and set 4, 4-, they are mounted upon a carrier (7 which in turnY is mounted inV connection with the movablei'support 2 withV capacity for shift or adjustment of such character that in one position Vof the said carrier the die 5 is presented as in Fig. 1 in position to coact with the piercer-spur in the manner shown in Fig. 3 in order to effect the piercing of thel work, while the set G is turned into an inoperative position; and that in a second position of the carrier, shown in Figs. 4 and 5, the die 5 occupies an inoperative position while the set 6 is presented in position to coact with the set 4a of the combined piercer and set ina setting operation.

The vconstruction providing for the adjustability of the carrier, to wliichrei'erence has just been made, may vary more or-less in practice in some cases. One specific feature vof-the'invention, howevei, consists in providing for the adjustability orp the carrier by mounting it pivotally in connection with the lower end of the movable support 2, as

shown in the drawings, so as to permitJ the 'said carrier to be swung from its position in 2 by means of its connected rock shaft 8,

which latter is fitted to bea-rings in a U- shaped bearing-piece 9 that is connected with the said support. The die 5 andv set 6 project from the carrier 7 at an angle to each other,`so that when either thereof is in working position the other thereof is turned into an inoperative position at one side or the other as the caseinay be. By turnin the carrier around the axis of the rock sha t the die and set are brought alternately into position for use. 4Provision isv made for holding the carrier in each Vof its positions of adjustment. In the present instance this means consists in a contracting spiral spring 10 having one end thereof engaged with a screw 11 projecting from the' front/oi the U-shaped bearing-piece 9, and the other end engaged with a stud 19. projecting eccentrically from a platel connected with one end of the rockshaft 8 and located at the front ofthe said bearing-piece. This stud l2 is locatedV upon the plate 13V in such angular relations with thedie 5 and upper setv that in the respective 'positionsofV swinging ad-V justment of the/carrier v7 Vthe said stud is located at one side or the other of a line drawn throughv the f aXis of the carrier. Consequently, the spring acts conti-actively in either of such positions oit' adjustment to keep the upper side of the carrier pressed against the top of the slot` occupied by theV carrier in the bearing-piece 9. .hen the slot in the bearing-piece. Thus the spring acts with equal efficiency to hold the carrier in either of the adjustment-positions into which it may be turned.

The work-backing 14 is mounted between the two supports 1 and 2, in a location adjacent the fixed support. In this case it is a spring-supported work-supporting table having a hole 15, Fig. 1, therethrough to accommodate the combined piercer and set 4, 4, and is mounted in place in connection with the said fixed support, and guided in its movements, by means of pins 16, 16, Figs. 1, 3, and 4, projecting downward from it and working in guide-holes in the said support. It is yieldingly sustained in its normal position, as Yfor instance 1 by means of expanding spiral springs 17, 17, shown in dotted lines, occupying central chambers in the said pins, and compressed between the upper ends of the said chambers and the lower ends of the said guide-holes. The springs may be combined otherwise with the work-backing in practice. They operate by their expansion to raise the work-backing automatically to its normal position from the lower position shown in Figs. 3, 4, 5.

Normally, the work-backing 14 occupies the position shown in Fig. 1, in which its elevation relative to the piercer-spur is suiicient to enable it to cover the point of the said spur. The hole 15 in the work-backing corresponds closelyin size with the size of the set 4, In ease it is desired to apply a washer g/ to the piercer-spur 4 before the piercing operation, this readily may be effected by placing the washer on the top surface of the work-backing and sliding it thereon over the hole 15, whereupon it will drop upon the piercer-spur and descend upon the latter until it rests upon the top of the said 4a, as in Figs. 1 and 7.

The described relation of the work-backing to the piercer-spur 4 in the normal position of the work-backing enables the work to be laid upon the upper surface of the work-backing and shifted about thereon until the portion thereof which is to receive the eyelet or other fastener is positioned properly with reference to the piercer-spur, etc. In the use of the machine, when the work has been laid upon the top surface of the work-backing, as in Fig. 1, so as to overlie the hole 15 in the work-backing, and the die 5 is brought down upon the work, thedownward pressure of the die upon the work will carry the Work and work-backing downward in unison, thereby in'ipaling the work upon the piercer-spur 4 as in Fig. 3, by forcing the work downward upon the piercerspur so that the latter will pass through the work into the interior of the die; and in addition forcing down the work-backing into a position on .a levelrwiththe set:4L at the base of the piercer-spur 4 as in said figure. 1n this condition of the parts the point of the piercer-spur projects at the upper side of the work and above the top of the workbacking. By the locking of the work-'backing in this depressed position it is held from rising as the die is raised from the work, and consequently when the upper support 2 is returned to its elevated position the workbacking remains down around the set 4 as in Fig. 4, and the point of the piercer-spur stands up above the top of the work-backing, rendering it easy for the operator to place an eyelet z, Fig. 4, upon the said point, as in said figure.

The latch or lock which in the present instance constitutes the means for automatically positioning the work-backing in the required relation to leave the point of the piercer-spur exposed above the work after the piercing operation, in readiness for the application of a fastener-member, such for instance as an eyelet, consists in the present instance in a latch 18, Figs. 5 and 6., mounted pivotally in connection with the fixed support 1 and adapted to engage with the work-backing. In this instance the said latch is arranged to engage an edge of a plate 19 attached to the under side of the Work-backing at a hole 20, which for convenience, is made in the work-backing to admit the top of the latch.

The latch 18 is spring-actuated to cause it to engage automatically with the workbacking, by means of a contracting spiral spring 21 having Aone end thereof engaged with a fixed point of attachment 22 in connection with the upright portion of the fixed head 3 of the machine, and the other end thereof engaged with an upright arm 23 fixed upon the journal or rock shaft 24 of the latch. This spring in contracting acts to hold the upright arm 28 against a stop 25 projecting' from the said upright portion of the fixed head, and thereby keeps the latch in a position to engage with the plate 19 on the work-backing as the workbacking is depressed through the action of the descending die against the work.

In the working of the machine, the latch operates to lock the work-backing in the retracted position of the latter relative to" the piercer-spur which is given thereto at the time of the piercing operation, as in Fig; 3, and it holds the wolk-backing in the said position as in Fig. 4 to facilitate the application of the eyelet or other fastener-member to the piercer-spur above the work, and until the setting operation has been effected.

rIhe automatic means whereby theworkbacking 14 is returned to thenorinal position after the setting operation comprises in this instance, as previously mentioned,

means for automatically unlatching or unlocking the work-backing so as to permit the actuating springs 17, 17, in connection with the work-backing to lift the latter to its normal position. The means for automatically unlatching or unlocking the workbacking consists in a trip 26 moving in unison with the movable support 2. This trip is combined and arranged to coperate in the descent of the movable support 2 for the setting operation so as through its engagement with the arm 23 fixed on the rockshaft 24 of the latch 18 to swing such latch out of engagement with the plate 19 carried by the work-backing, so as thereby to free the work-backing to the action of its actuating springs 17, 17, which thereupon raise the work-backing to its normal position shown in Fig. 1 covering the piercer-spur et.

The trip 26 is made inoperative forthe stroke of the support 2 'for the piercing operation, and made operative for the stroke of said support for the setting operation, by being moved into and out of engagementrelations with the arm 23 of the springactuated latch 18. In the illustrated embodiment, the said trip is a projecting portion or extension of the rear end of the rock shaft 8 of the carrier 7 for the die 5 and upper set 6. This extension is eccentrically disposed with relation to the axis of the said rock shaft, so that in one position thereof, namely, that which is assumed by it when the carrier 7 occupies the position shown in Figs. 1,2 and 3, with the die 5 in position to act and the set 6 turned into an inoperative position atV one side, the trip 26 will occupyl such a relation with respect to the arm 23 that in the descent of the movable support 2 for the piercing operation the said trip will pass down at one side of the arm 23, Without actuating the said arm and latch to disengage the latch from the work-backing; while-in the position of the carrier 7 which places the upper set 6 in position to operate for setting purposes and disposes the die 5 at one side in an inoperative position as in Figs. tand 5, the trip 26 occupies a position to engage with the arm 23 asthe movable support 2 descends for the setting operation, and consequently through such engagement with the said arm the arm will be pressed to one side and the latch will be disengaged from the workbacking.

As soon as the latch in disengaged from the work-backing so as to unlatch or unlock the workebacking, thelatter will be raised by the action of its springs 17, 17, and as it is moved upward it will push the work upward so as to disengage it from the piercerspur 4.
